Ecology Vocab
The study of relationships between organisms within an ecosystem
What is Ecology?
Movement of the products of weathering to a different location
What is erosion?
A farmer keeps losing all of his soil due to wind. What is ONE way that he could keep his soil safe?
Windbreak OR no-till farming OR crop-rotation
The process by which a stream dumps sediment is called:
Deposition
Planting trees in rows to protect soil from erosion
What is Windbreak?
Which of the following can cause erosion?
A) Wind
B) Water
C) Ice
D) All of the above
A farmer on very hilly land wants to maximize his planting area. What is ONE way he could do this?
Contour Farming OR terracing.
When soil moves down a hill it is called:
Erosion
Planting different crops from season to season in the same area
What is Crop Rotation?
Small bits of rock and soil that are carried away by water, wind, or ice.
What is sediment?
A family keeps losing their land due to erosion from their river. How can they keep their property safe?
Riverbank Stabilization.
A slow movement of soil down a hill causing trees to lean is called:
Creep
Planting crops perpendicular to the curve of the land; farming at equal elevation
What is Contour Farming?
What is the difference between weathering and erosion?
A) Weathering is the breaking down of rocks, and erosion is the movement of those broken pieces.
B) Weathering and erosion are the same thing.
C) Weathering happens only with wind, and erosion only happens with water.
D) Erosion happens only in deserts, and weathering only happens in mountains.
Why would somebody do channelization?
To keep rivers/streams from eroding land.
If you see a pile of broken rocks at the bottom of the cliff you should look for:
A rockslide
The accumulation of eroded sediments
What is Deposition?
A way to prevent erosion from happening at the beach.
What is coastal stabilization.
What would one disadvantage be to build your house on a rocky hill?
You could be victim of a rockslide and lose your property.
After a heavy rain, a steep hillside made of loose dirt may experience what?
A mudslide.
